IMPROVEMENT IN DOORS FOR GRAIN-CARS.

Specification forming part of Letters Patent No. 165,490, dated July 13, 1875; application tiled May S, 1875.

To all uhom it may concern Be it known that I, FREDERICK J. Kin- BALL, of Philadelphia, in the county ot' Philadelphia and State ot' Pennsylvania, have invented a new and Improved Grain-Door for FreightCars, of which the following is a specifica-tion The invention consists in the arrangement of a swinging bar, a pivoted latch for locking its free end, and permanent or fixed vertical bars, whereby the door is secured and also adapted to be opened outward, in the manner hereinafter described.

Figure 1 of the accompanying drawing is a front view ot' car-door, showing grain-door in position. Fig. 2 is a horizontal section on line m w. Fig. 3 is a vertical section on line y y. Fig. 4 is a vertical section on line z z.

Similar letters of reference indicate corresponding parts.

The supports for the door A consist, iirst, of strips or plates of iron,B, or wood, fastened on the back of the door-posts G, and projecting beyond the posts a sufficient distance to prevent the door from falling inward before the grain is putin. Second, on the inside'ot` one post is a wooden or iron strip or bar, D, fastened permanentlyto the post, allowing` sufficient space between it and the strip or plate on the back of the post for the grain-door.

On the other post is fastened, by a bolt, F, rivet, or otherwise, a swinging bar of wood or iron, so arranged that it can be held down when the door is in position by a latch, G, or sliding bolt, and when the door is to be opened to raise the latch or bolt, swing the bar out, and the door is then free to open out. This bar E, and also the permanent strip D on the other post, can be made of wood, or wood and iron, or of wrought or cast iron. The latch is so arranged that the pawl has a projection, iitting in a groove in the body of the latch, in order to give additional support. It is also so arranged that it can be bolted or fastened to the door-post, and also through the side Stringer ot' the car. It' required, the groove or depression to receive the pawl can have an outlet or be extended through the body of the latch, in order to allow the grain or dirt that may accumulate there to be cleaned out.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The swinging bar E, latch Gr, and permanent bars D and B, combined with the door, substantially as specified.
